Whether you need to unblock a single day or multiple days, the steps are the same. You need to unblock one day at a time.
To unblock a day you can use any of these 4 calendar views: Month, Week, Day, Location. This tutorial will walk you through unblocking through your calendars Month view.
Click on Calendar > Month view.
Go to the month and day you want to unblock. In this case April 4th, 2022.
Left click on the 4th and choose Unblock Date.
You will not see that April 3rd, 2022 is no longer a blocked day.
